DEFINITION

Classification: 523/324

Utilizing a treatment zone specifically described by shape

(other than nominally helical) or at least a part of which zone is specifically described by dimension, material, proportion, or angle of orientation:

(under subclass 1) Process wherein a desired or intentional composition is treated or formed utilizing a treatment zone or vessel or portion of zone or vessel specifically described by shape (other than nominally helical, dimension, material, or angle of orientation to the earth or other surface.

(1) Note. Mere statement that a vessel is made of metal or plastic is not sufficient for this subclass, however, specific classes of metals or plastics, e.g., noble metal or polyolefin, etc., would be.

(2) Note. Relative statements of size, e.g., large, small, thick, thin, etc., are not given weight unless a relative proportional statement is made, e.g., base is three times wider than the height, etc.

(3) Note. Angle of orientation relates to the earth or some other surface, e.g., vertical, upright, normal, horizontal, level, inclined, slanted, sloped, pitched, etc., these terms are assumed to relate to the earth's surface. Angle of orientation of a zone can be used to described the orientation of the longer axis of the zone or vessel.

(4) Note. If no angle of orientation is stated in the claim then classification will be made on another basis.

(5) Note. Reference to a class of treating apparatus, e.g., roll mill, ball mill, etc., is not a specific shape or description sufficient for this subclass; however, a roll of 6 inches in diameter would be sufficient. See (6) Note.

(6) Note. The dimension of the zone or vessel relates to the size, volume, cross-sectional area or proportional relationship. An example of a proportional relationship would be the description of a helical zone by relative arrangement of helical flights. (7) Note. Specific shape of the zone or vessel other than merely "helical" is sufficient for this subclass. Also excluded are the nominal terms "extruder", "screw extruder", or "worm extruder".

(8) Note. Ball, hammer, or rod mills, are excluded herefrom since these terms do not specifically describe the shape of the zone or vessel.

(9) Note. Mere statement that a zone or vessel is "elongated" is not sufficient.
